Rain gutter dredger and use thereof

A system for de-clogging a rain gutter and a downspout coupled to said rain gutter, said system comprising:

• a motion device and a cleaning device comprising a cleaning member functionally coupled to said motion device,
• wherein said motion device is configured to drive uni-directional motions or oscillating motions of said cleaning member based on motions of a liquid flowing through said rain gutter and said downspout and through said motion device caused by gravity,
• wherein said motion device comprises:
• a set of motion wheels coupled to said cleaning member of said cleaning device,
• or,
• a device housing having an upper end and a lower end distal to each other along a longitudinal axis of said device housing, a partition member for forming a first partition and a second partition, each is parallel to said longitudinal axis, and a direction device for opening and closing said first partition and said second partition in alternate.

A kit for a system for de-clogging a rain gutter and a downspout coupled to said rain gutter, said kit comprising a motion device selected from:

• a first motion device comprising a set of motion wheels configured to be coupled to said cleaning member of said cleaning device;
• a second motion device comprising:
• at least a device housing having an upper end and a lower end distal to each other along a longitudinal axis of said device housing, a partition member for forming a first partition and a second partition, each is parallel to said longitudinal axis, and a direction device for opening and closing said first partition and said second partition in alternate;
• and
• a first motion member positioned in said first partition and a second motion member positioned in said second partition, said first and said second motion member are coupled together via a motion member coupler and each is movable parallel to said longitudinal axis, said first motion member is configured, when it moves downward, to pull said second motion member moving upward via said motion member coupler and, in alternate, said second motion member is configured, when it moves downward, to pull said first motion member moving upward via said motion member coupler;
• wherein, said direction device is configured to open said first partition and close said second partition when said first motion member is near said upper end and said second motion member is near said lower end, in alternate, said direction device is configured to open said second partition and close said first partition when said second motion member is near said upper end and said first motion member is near said lower end, and said direction device is configured to open only one of said first and said second partition at a time;
• wherein, said first partition and said second partition are positioned in said device housing;
• or
• said first partition is positioned in a first device housing and said second partition is positioned in a second device housing;
• or a combination thereof;
• wherein said motion device is configured to produce uni-directional motions or oscillating motions based on motions of a liquid flowing through said motion device caused by gravity when assembled.
